Woodyard Debarking Drum Wear Solutions

Debarking drums in a pulp & paper woodyard encounter heavy impact and high stress grinding abrasion around the clock.


The lifter bars shown in this debarking drum encounter round-the-clock wear as the logs are tumbled to knock off the bark. The lifter bars are made from 3” square QT-Plus ®.

Papermill woodyards work hard to reduce the amount of bark remaining, called ‘brown wood’, before going into the chipper. Most mills target 2% to 4% remaining bark. If the ‘brown wood’ with bark on the chips content is higher, they need to treat it with chemicals to achieve the required whiteness level for the finished paper product.

Depending on the make of the drum, many lifters are made from Manganese, which takes impact well. Manganese wears quickly from abrasion, until it has undergone substantial impact. The majority of the wear on Manganese happens in the first few weeks.

JADCO QT-Plus ® is the same hardness throughout the steel, so it battles both impact and abrasion wear immediately. This gives you progressive wear compared to commodity AR400 or AR500, which is softer in the center of the steel as it is on the surface.

This is why you may have witnessed your newly installed steel look great for 4 or 5 months, then it all but disappears over the next few weeks. What has happened is the thin harder outer layer has worn away, and the softer center of the steel wears rapidly.


Their steel is softer in the center than it is on the face of the steel, like an Oreo ® cookie.

JADCO’s QT Plus ® delivers greater performance IN YOUR WEAR APPLICATIONS than the various AR400 steel plates you have used previously.

Being able to create wear resistant steel having the same hardness through the entire thickness of the steel, demands you accurately control the alloying chemistry with precise heat treating.

Why Doesn’t Every Steel Company Make Their Wear Materials Last As Long As JADCO QT-Plus ®?

Most steel wear plate distributors choose to limit the proper quantities and percentages of these essential alloying elements. Their goal is a lower price than longer wear life.

They are planning to always sell you more of the same underperforming steel in a few months, happily stealing more of your hard earned profits.

For over the last 40 years JADCO has focused exclusively on delivering consistent, longer equipment life for our customers.

Now you understand why we are able to deliver better results to our customers. We think differently by strictly focusing to improve your current results.
